[PATCH 00/26] leon: various fixes and TN0018 errata workaround

[Daniel Hellstrom]

Hi,

The GRLIB-TN-0018 errata (gaisler.com/notes) was recently published and
affecting the LEON3FT devices like UT699, UT700 and GR712RC. RTEMS SW
workarounds were released in May/June in the RCC dists so now I would
like to request to upstream that work and other differences between the
RTEMS5 code base for RCC-1.3.

Apart from fixes there is also driver support for the new CAN-FD in
GRLIB: GRCANFD. The restructuring of the CAN code is also an improvement
for GR712RC and GR740 by sharing more common code.

The patches are also found in the submit/20200629 branch of rcc.git:
  https://git.rtems.org/danielh/rcc.git/log/?h=submit/20200629

Please let me know if I should separate the patches in smaller chunks
and resend or any other comments. As most are fixes I didn't do that
initially.

I've just learn that RTEMS5 branched! It would be great if the patches
could go on both master and 5.

Kind Regards,
Daniel Hellstrom
